What is an optomap Image?

Downtown Victoria Optometry is thrilled to introduce its newest piece of diagnostic equipment, the Optomap Daytona. This device is used to image the retina (the layer lining the back of the eye) and captures a detailed 200° degree image, where as traditional methods only encapsulate 45°.

Getting an Optomap image is fast, painless, and comfortable. It is suitable for individuals of all ages, even children. Nothing touches your eye at any time. Also, under certain circumstances, dilation drops may not be necessary, but that is completely up to your eye care practitioner.

Remember, the retina is the only place in the body where blood vessels can be seen directly. This means that in addition to eye conditions, signs of other diseases (for example, stroke, heart disease, hypertension and diabetes) can also be seen in the retina, often without any symptoms. These are only a few reasons why an Optomap is beneficial.

Visual Field Perimetry Testing Equipment (Visual Field Perimeters)

Visual Field Perimetry Testing Equipment are used by eye doctors to look for signs of vision loss in patients. During the non-invasive test, a patient sits and looks inside the instrument at a screen. Every time the patient sees a flash of light, they are instructed to press a button on a remote. In this way, the patient’s entire vision — including their peripheral or side vision — is checked, as a loss of peripheral vision can be an early indicator of glaucoma.

Visual Field Test

A visual field test is an eye examination that can detect dysfunction in central and peripheral vision which may be caused by various medical conditions such as glaucoma, stroke, pituitary disease, brain tumours or other neurological deficits. Visual field testing can be performed clinically by keeping the subject’s gaze fixed while presenting objects at various places within their visual field. When dedicated machinery is used it is called a perimeter.

The exam may be performed by a technician in one of several ways. The test may be performed by a technician directly, with the assistance of a machine, or completely by an automated machine. Machine based tests aid diagnostics by allowing a detailed printout of the patient’s visual field.

Exam Overview

A perimetry test (visual field test) measures all areas of your eyesight, including your side, or peripheral, vision.

To do the test, you sit and look inside a bowl-shaped instrument called a perimeter. While you stare at the center of the bowl, lights flash. You press a button each time you see a flash. A computer records the spot of each flash and if you pressed the button when the light flashed in that spot.

At the end of the test, a printout shows if there are areas of your vision where you did not see the flashes of light. These are areas of vision loss. Loss of peripheral vision is often an early sign of glaucoma.

A perimetry test can help find certain patterns of vision loss. This may mean a certain type of eye disease is present. It is very useful in finding early changes in vision caused by nerve damage from glaucoma.

Regular perimetry tests can be used to see if treatment for glaucoma is preventing further vision loss.
